Though he hasn’t announced any plans to run for office, Facebook founder Mark Zuckerberg’s penchant for hiring high-profile wonks makes it seem all the more likely that he’ll be running for president soon.

He was hired to conduct research for the couple’s philanthropic Zuckerberg-Chan initiative, but paired with hiring Obama’s former campaign manager David Plouffe as their policy director, the move towards politics seems all the more likely.

Along with Plouffe, the couple also hired Amy Dudley, former communications adviser to Clinton’s running mate Sen. Tim Kaine (D-VA), earlier this year.

In a Facebook post from Iowa (the traditional first stop on presidential campaigns based on their early caucus date), Zuckerberg said he isn’t running for president, but as Politico noted, his name has floated as potential candidate “along with just about every other billionaire or elected official with half the name recognition of a second-tier Trump adviser.”
